(4.2.32.3)android热修复之Andfix方式:Andfix的初步使用

使用一览

代码引入

  • 引用
dependencies {
    compile 'com.alipay.euler:andfix:0.3.1@aar'
}

或者

使用module的方式添加andfix,这样可以直接查看编辑源码。记得新建jniLibs文件夹,将AndFix里面的libs里的so文件移到jniLibs里。
  • 初始化
patchManager = new PatchManager(context);
patchManager.init(appversion);//current version
  • 加载补丁,尽量在 Applicat ion 的 onCreate 方法中使用
patchManager.loadPatch();
  • 应用补丁
patchManager.addPatch(path);//path是补丁的存放路径

ProGuard混淆

  • Andfix使用到的native方法类
com.alipay.euler.andfix.AndFix
  • 注解保留
com.alipay.euler.andfix.annotation.MethodReplace
  • 添加混淆文件声明
-keep class * extends java.lang.annotation.Annotation-keepclasseswithmembernames class * { native <methods>;}

使用生成patch工具类命令

项目中提供了一个生成补丁(后缀为 .apatch )的工具 apkpatch

  • 生成补丁
usage: apkpatch 
-f <new> -t <old> -o <output> -k <keystore> -p <***> 秘钥密码 -a <alias> -e <***> 别名密码 
-a,--alias <alias> keystore entry alias. -e,--epassword <***> keystore entry password. -f,--from <loc> new Apk file path. -k,--keystore <loc> keystore path. -n,--name <name> patch name. -o,--out <dir> output dir. -p,--kpassword <***> keystore password. -t,--to <loc> old Apk file path.

例如:

./apkpatch.sh -f /Users/e0uoq/AndfixDemo2/app-release.apk -t /Users/e0uoq/AndfixDemo2/app/app-release.apk -o /Users/e0uoq/andfixpatch -k /Users/e0uoq/andfixkey.jks -p andfix_key -a andfixsign -e andfix_sign
  • 此外还提供了apatch合并的命令,将多个apatch合并为一个
usage: apkpatch 
-m <apatch_path...> -o <output> -k <keystore> -p <***> -a <alias> -e <***> -a,--alias <alias> keystore entry alias. -e,--epassword <***> keystore entry password. -k,--keystore <loc> keystore path. -m,--merge <loc...> path of .apatch files. -n,--name <name> patch name. -o,--out <dir> output dir. -p,--kpassword <***> keystore password. 

适用场景

实例演示

前提是环境基本已经配好

1-Application中进行初始化

package com.example.lhx.andfixdemo;  

import android.app.Application;  
import android.os.Environment;  
import android.util.Log;  

import com.alipay.euler.andfix.patch.PatchManager;  

import java.io.File;  
import java.io.IOException;  

/** * sample application * */  
public class MainApplication extends Application {  
    private static final String TAG = " andrew";  

    private static final String APATCH_PATH = "/out.apatch";  

    private static final String DIR = "apatch";//补丁文件夹 
    /** * patch manager */  
    private PatchManager mPatchManager;  

    @Override  
    public void onCreate() {  
        super.onCreate();  
        // initialize 
        mPatchManager = new PatchManager(this);  
        mPatchManager.init("1.0");  
        Log.d(TAG, "inited.");  

        // load patch 
        mPatchManager.loadPatch();  
        try {  
            // .apatch file path 
            String patchFileString = Environment.getExternalStorageDirectory()  
                    .getAbsolutePath() + APATCH_PATH;  
            mPatchManager.addPatch(patchFileString);  
            Log.d(TAG, "apatch:" + patchFileString + " added.");  

            //复制且加载补丁成功后,删除下载的补丁 
            File f = new File(this.getFilesDir(), DIR + APATCH_PATH);  
            if (f.exists()) {  
                boolean result = new File(patchFileString).delete();  
                if (!result)  
                    Log.e(TAG, patchFileString + " delete fail");  
            }  
        } catch (IOException e) {  
            Log.e(TAG, "", e);  
        }  
    }  
}  

2-生成不同的新旧包

demo的场景就是一开始点击确定按钮textview显示I am old.然后假设这个方法有问题,我改为I am new.区分新包和旧包。

打包1.apk后,修改textviewt内容,打包2.apk

package com.example.lhx.andfixdemo;  

import android.app.Activity;  
import android.os.Bundle;  
import android.view.View;  
import android.widget.Button;  
import android.widget.TextView;  


/** * main activity */  
public class MainActivity extends Activity {  
    private TextView mShowTextView;  
    private Button mSureButton;  

    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        mShowTextView = (TextView) this.findViewById(R.id.show_tv);  
        mSureButton = (Button) this.findViewById(R.id.sure_btn);  

        //打包1.apk后,修改textviewt内容,打包2.apk 
        mSureButton.setOnClickListener(new View.OnClickListener() {  
            @Override  
            public void onClick(View v) {  
                mShowTextView.setText("I am new");  
            }  
        });  
    }  
}  

3-混淆

# Add project specific ProGuard rules here.  
# By default, the flags in this file are appended to flags specified  
# in E:\android_sdk/tools/proguard/proguard-android.txt  
# You can edit the include path and order by changing the proguardFiles  
# directive in build.gradle.  
#  
# For more details, see  
#   http://developer.android.com/guide/developing/tools/proguard.html  

# Add any project specific keep options here:  

# If your project uses WebView with JS, uncomment the following  
# and specify the fully qualified class name to the JavaScript interface  
# class:  
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {  
#   public *;  
#}  
-optimizationpasses 5 # 指定代码的压缩级别  -dontusemixedcaseclassnames # 是否使用大小写混合  -dontskipnonpubliclibraryclasses # 是否混淆第三方jar  -dontpreverify # 混淆时是否做预校验  -verbose # 混淆时是否记录日志  -optimizations !code/simplification/arithmetic,!field/*,!class/merging/* # 混淆时所采用的算法  
#重要,別忘了這些,不混淆andfix包,不混淆native方法  
-dontwarn android.annotation -dontwarn com.alipay.euler.** -keep class com.alipay.euler.** {*;} -keep class * extends java.lang.annotation.Annotation  -keepclasseswithmembernames class * {      native <methods>;  
}<span style="font-size:18px;"></span>  

4-使用工具打包补丁文件:apkpatch-1.0.3

  1. 注意要把你的keystone文件,新包和旧包一同放在apkpatch-1.0.3文件里面。这里注意下,apk指的是没有经过第三方加固的。
  2. 然后win+R调出cmd命令
  3. 这里对命令先做一个简单介绍,后面也会特意分析这个打包工具。
    apkpatch.bat -f new.apk -t old.apk -o output -k lhxtest.jks -p 123456 -a 123456 -e 123456
  4. 命令成功后,会在目录下生成一个输出文件夹,文件夹里面就有扩展名为.patch的文件,把它改为out.patch.(PS:新手不熟悉命令行的话,记得一定要cd到apkpatch-1.0.3目录下,你可以直接cd然后加上那个目录的路径就可以了,然后再输入命令)
  5. 为了检测,首先运行旧包,然后把out.patch文件负责到在手机根目录下,再重新打开app,你会发现点击确定按钮,textview显示为”I am new”就表示方法修复成功了
